    AHCI and Windows 7 after installation


    I recently discovered that my system had defaulted to IDE when install Windows 7 Pro 64bit for the first time from an ASUS P6T SE.

    I found that you could edit the registry to enable SATA and AHCI after the fact, so I was able to perform this. I installed the SATA drivers for JMicron controller, rebooted windows, then rebooted and enabled AHCI and SATA for the drives (WD SATA & Samsung SATA). This seemed to work correctly as I can now see my SATA drives as hotplugged (eject from taskbar). When I go into device manager, I still see a whole whack of IDE channels with the HDDs under them along with the MS AHCI driver and the JMicron Controller in Storage Controllers.

    Here's, a screenshot to see if I did this correctly. Should I uninstall the IDE controllers and let Windows sort it out on reboot.. I'm a little lost at this. I don't really want to format and reinstall everything, but I'm willing to do it if necessary.

    Thanks.

    I think I figured it out for myself, but I'll let you guys confirm. When I switch to 'resources by connection' in device manager, the two HDDs do appear under the AHCI SATA controller..

    I suppose you can delete this thread. Went into SiSoft Sandra and it reported both drives were SATA G2 300Mbps.

    Just a follow up to me solving this issue. I can't seem to get Windows 7 Pro x64 to switch to the JMicron AHCI driver over the MS AHCI 1.0 driver. Is there a reason why its not migrating? I did a little digging and a review noted that the manufacturers drivers were usually a little faster than the one from MS. Can I use the Intel chipset drivers with this controller or does it have to be JMicron specific?
